WEB-FEEDING MECHANISM.

Specication of Letters Patent. Patented -:Maly 30, 1916.

Application led September 12, 1910. Serial No. 581,666.

To all whom t may concern; Be it known that I, EDWARD STINE, a citi- 'zen of the United States, residing at Richmond Hill, in the county of Queens and State of New York, have invented certain new and useful Improvements in Web- Feeding Mechanism, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to feed rollers and with regard to its more specific features to devices of this character employed in connection with printing presses.

One of the objects of the invention is to provide a device of this character by means of which an even and positive grip is applied to the paper throughout the full width thereof; thus two or more webs may be fed without danger of offset, perfect registration being insured.

-Another object is to provide means whereby the adjustment of one of the feed rollers with respect to the other is even and positive, thereby assuring uniform tension. Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations ofl elements and arrangement of parts which will be exemplied in the construction hereinafter. set forth, and the scope of the application of which will be indicated in the following claims.

In the' accompanying drawings, wherein is shown one of various possible embodiments of this invention, and in which similar reference numerals refer to the same tion of the device, parts being broken away parts throughout, Figure 1 is a front elevafor the sake of clearness, and Fig. .2 is an end view of .the same, the pulley being broken away for the sake of clearness.

Referrmg now to Fig. 1 of the drawings, l indicates a feed roller journaled in asuitable frame 2 and having secured thereto atl one end agear 3. Its companion roller 4..:

' ,is journaled in bearings '5 sliding in slots 6 formed in the frame 2 and normally held in raised position by suitable springs 7 which engage the bearings and maybe seated in recesses 8 formed in the frame.

At one end of roller 4 al gear 9 is secured, which meshes with the gear 3 secured to the first roller. Motionmay 'be communicated to the rollers by any suitable means, as, for example, by pulley 10 mounted upon an extension of the shaft of the roller 4. The

-surfaces of the two rollers are provided with a vplurality of longitudinal and circumferential V-shaped grooves 11 and 12 thus providing said rollers with roughened surfaces. Pins 13 sliding in the frame 2 engage with the sliding bearings .6 and are preferably provided with enlarged -heads 14 with which cams 15 secured to the shaft 16 engage, said shaft rotating in bearings '17 which slide in slots' 18 yformed in the rotated so that the portions 25 are out of engagement with the pins :13 the set-screws 24 may be manipulated to cause the surfaces of the cams to press against the pins 13, and thereby move the roller 4 into the desired proximity with the roller 1, then by rotating the handle 19 the shaft 16 may be rotated to bring the eccentric portions 25 of the cams into engagement with pins '13, and these eccentric portions are so designed that thisV moveme'nt'of the handle will force the upper roller 4 downward'in such relation to the vunder roller as to give the desired pressure between the rollers for the drawing of the .webs 26 between them.

The operation ofthe device is as follows: Afterthe adjustment has .been made as above described, the cams are rotated to re- -move their eccentric portions 25 from the pins, thus enabling the springs 7 to move the upper roller 4 slightly to permit of the webs of paper 26 being threaded between it and the lowerroller 1, after which the cams `are then rotated to bring their eccentric portions in contact with the Pins, whereby the upper rolleris depressed as above described and the proper pressure is obtained.

While three webs are shown at 26 as being fed through the feeding rollers, it will, of course, be understood that 'a greater or less number vmay be employedif desired frame 2. The cams are eccentric, and when those in which the operation is rapid.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

Having described my invention, what l claim as new and desire to secure by Letters Patent is:

l. in a device of the-class described, in combination, a plurality of coacting feed rollers adapted to feed a plurality of registering webs, each of said rollers being provided with a plurality of sets of relatively close V-shaped grooves intersecting each other at right angles whereby sets of points engaging the4 webs are formed upon the rollers. 4

:2; ln a device' of the class described, in combination, a frame, a roller journaled therein, a second roller co-acting with said first -roller and jourri-aled within bearings, said bearings being slidingly mounted within said frame, springs tending to l"move `said bearings in one direction, slidable means engaging said bearings and -adapted upon actuation-to move said bearings inthe opposite direction, and 'oscillating means for moving said last-mentioned means whereby said bearings will be simultaneously moved to provide an even adjustment of said second roller with'respect to said first roller.

3. In a device of the class described, in combination, a frame, a roller journaled therein, a second roller coacting with said first roller and journaled within bearings, said bearings being slidingly mounted within said frame, springs tending to move said Lieaae bearings in one direction, slidable means engaging said bearings and adapted upon actuation to move said bearings in the opposite direction, and oscillating means for simultaneously moving said last-mentioned means whereby said bearings will be simultaneously moved to provide an even adjustment of said second roller with respect to said first roller.

4. in a'device of the class described, in combination, a frame, a Yroller yjournaled therein, a second roller coacting with said first roller and journaled within bearings, said bearings being slidingly mounted within said fra-me, slidable means engaging said bearings, a shaft mounted in bearings slidable on said frame, means carried by said shaft engaging. said slidable means and adapted to actuate the same, means for rotating said shaft, and adjusting means for said shaft bearings.

5. ln a device of the class described, in combination, a plurality of feed rollers adapted t0 feed a plurality of registering webs and means comprising pointed projections associated with the surfaces of said rollers\y coacting with the webs whereby a relative slipping of the webs as the same are fed is positively prevented, said rollers being arranged to. bringl the pointed projections of one roller in contact with the pointed projections ofthe other.

6. ln a device of the class described, in combination, a frame, bearings mounted in said frame, a pair of coacting feed rollers having roughened surfaces mounted in said bearings, the bearings in one of said rollers being slidably mounted within said frame, a shaft mounted in said frame, bearings for said shaft, coacting means between the shaft and the movable bearings o'f one of said rollers for urging the roughened surfaces of said roller into closer engagement when said shaft is rotated, and means for adjusting the relative position of the bearings of said shaft.
